Indeed nord.
One last one, and it was a humdinger
Garden Of The Dead (1972, John Hayes)
What a find (YT). Only an hour! (CUT??)
A load of prisoners plan a breakout on the eve of being transferred to another facility. They also start huffing
formaldehyde ahem. This puts a slight cramp in their plans later on
Plus the mixed messages they get from authority figures (one gets to cuddle a partner just outside the gate, others get shot point blank when discovered escaping!!) can't help their frame of mind. As US regional horror goes, this was par for the course, even if a few scenes stood out for sheer effort hahaha. An ODDITY.
